car: 91 crx Si w/ b16a1 swap..

Problems: when i first start the car it takes a few seconds to start up and when it does it starts a really low rpm like 500 unless i give it a little gas..

2nd problem: once the car has started and i drive for a couple minutes and i go to a stop light the car will stay at a grand for a little then will drop down to 500 and then 300 and start to act like its going to cut off and then i give it a little gas and it goes to a grand and then does the same thing...

 

adjust your idle...

 

When life passes you by..downshift into VTECH


its vtec.

 

i apologize for my mispelling of vtec..the brand of phone i have is vtech and it was just coincidence that it was sitting right infront of me when..o f*ck it no since in trying to deffend myself

 

possible vac leak. check your IACV an your FITV too

 

+1

beat me to it. If your hood is unpainted, you should have a diagram (even though its for the d16) and just make sure all vacuum lines are run correctly. 90% of the time, its you have a tube not hooked up or in the wrong spot.

 

Vaccum leaks generally increase the idle though so I am leaning towards the idle screw...

 

Definitely check idle, and all your vaccuum lines and report back. I'm also going to change your thread title, as it's not quite "work-friendly".

 

Could also be timing. Would have to here it also. Have you had a valve adjustment done recently?

 

either advance your distributor a little or adjust your idle air screw if u have one!
